Project description:Rothia aeria is a recently described Gram-positive rod from the family Micrococcaceae. An elderly woman with rheumatoid arthritis and dental abscesses who was undergoing immunosuppression had R. aeria isolated from synovial fluid. This report characterizes this rare organism and contributes to the literature on its pathogenicity and likely oral source.
Project description:Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, endocarditis by R. aeria was complicated by central nervous system embolization. In the case we report herein, endocarditis by R. aeria was diagnosed after acute self-limited diarrhea. In addition to the common translocation of R. aeria from the oral cavity, we hypothesize the possibility of intestinal translocation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry and genetic sequencing are important tools that can contribute to early and more accurate etiologic diagnosis of severe infections caused by Gram-positive rods.
